Using Raspberry PI 3B+ unable PING from LAN to WAN

Configuration: 8 Raspberry PIs (series 4) as a home lab connected to an 8 port switch. I am attempting to use the 3B+ LAN side for local traffic and the WAN side for the internet. I am able to ping IP addresses from LAN to WAN but unable to ping ex. from the LAN side to the WAN side. I would like to have the internet side connected to the LAB environment so I don't have to be directly connected. Needing help with setting this up. What do I need to enable to give me the ability to ping\connect to the devices from the internet side? When I say internet I mean home network.
I am using the following image - openwrt-22.03.0-rc6-bcm27xx-bcm2710-rpi-3-ext4-sysupgrade.img

It sounds like you have a DNS problem.
